2 Claims. (Cl. 257-263) This invention relates to a unit for use in a sad iron or pressing iron for generating steam therein which is caused to issue from ducts in the pressing face of the iron.

The principal object of the invention is the provision of a unit of the indicated character constituting a structural integrality affording an intimate metallic Contact between a suitable body and a pipe or tubing, so as to obtain a maximum steam generating efficiency.

The advantages of the use of a unit of the character mentioned are the low cost of production, and the low cost of incorporating the unit in the iron.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing in which Fig. l. is a longitudinal section showing a unit embodying the inventionin use in a pressing iron portions of which are broken away, the section being taken approximately on the line I-I of Fig. 2;

Fig. 2 is a section taken on the line 2-2 of Fig. 1;

Fig. 3 is a section taken on the line 3-3 of Fig. 2.

The unit of the present invention includes a single piece of piping or tubing I0 of any suitable metal, preferablycopper. The pipe or tubing I0 may be bent into any desirable form or shape so as to provide a maximum heating surface in a comparatively small area. The pipe or tubing I0 may be bent zig-zag, or be looped as shown in the present instance. It is also to be understood that the pipe or tubing Ill may be so bent or coiled as to produce two or more layers superposed with respect to each other. In the present instance there is shown by Way of example a one-layer coil. In accordance with the invention use, is made of a mass of suitable molten metal, preferably aluminum or white metal, which is cast about the pipe or tubing I0 so as to be in intimate contact therewith, and to form a solid body. This body is designated II. The body II may take any desired shape, but is preferably the shape of the usual sadiron or pressing iron having a straight rear end, and sides converging to a point at the front, shown most clearly in Fig. 2.

In producing-the unit, the pipe or tubing bent to the desired form will be placed in a suitable mold after which the selected molten metal is poured into the mold for the purpose of casting the metal about and in intimate contact with unit nts.

the pipe or tubing, and to form a solid body. In the present instance the upper and lower surfaces of the body II are flat and parallel to each other. The body II also has an opening I2 therein which is within the confines of the 5 innermost coil of the pipe or tubing I0, in order to accommodate suitable fastening elements for the purpose of securing the unit in place. The opposite ends of the pipe or tubing I0 are left available to provide for the inlet of water to the 10 pipe or tubing, and to provide for the outlet of steam therefrom. In the present instance thev opposite ends of the pipe or tubing project from the cast body I I at different points and in different directions. One end I3, the inlet end, prol5 jects rearwardly at one side of the body II, and the other end i4, the outlet end, projects forwardly into the opening I2.

The unit having the features set forth is designed and adapted to be arranged between a 20 bottom or pressing section I 5 and a top or cover section I6 of a pressing iron, as shown in Fig. l. Thesection I5 has a recess therein in which the Heat is produced by an electric heater unit I'I arranged between the section I5 and the 25 body I I. The outlet end I4 of the pipe or tubing IIJ is in communication with a bore of a plurality of inter-communicating bores in the section I5, by a coupling I8. Certain of the bores have ducts leading therefrom through the press- 30 ing face of the section I5 to liberate the steam, all of which is common practice. The inlet end I3 of the pipe or tubing I0 has connected therewith controllable water feeding means of any preferred type, the same being designated gen- 35 erally by the reference numeral I9. The sections I5 and I6 together with the heater and steam generating unit are fastened together by bolts 20 carried by the section i5 and extending through the opening I2 in the body ll and pass- 40 ing through holes in the section I6, nuts being applied to these bolts 20 which also serve to secure the usual handle of the iron.

From the foregoing it will be obvious that water is fed to the pipe or tubing Ill through 45 the inlet end I3 thereof, which is converted into steam by the heat produced by the heater I1, finding its way to the pipe or tubing I0 by conduction through the body I I which is in intimate contact with the pipe or tubing I0. The steam passes from the outlet end I4 of the pipe or tubing I0 to the pressing face of the iron through the communicating bores and ducts hereinbefore mentioned.

I claim:

1. Por use in, generating steam in a pressing iron, a metal pipe, and a mass oi' metal cast about and in intimate contact with the pipe, and

5 forming a solid body having an opening therethrough, the opposite ends of the pipe projecting from said body, one of said ends serving for receiving water and the other end projecting into said opening and serving for delivering steam.

2. For use in delivering steam in a pressing SAMUEL DOWINSKY.
